摘要: The decomposition of polyurethane, measured gravimetrially or using infrared spectrophotometry, was found to be more complete in polyurethane based on polyester and only very small polyether. In the presence clay minerals inhibited. If positive, followed sequence: remaining free isocyanates→urea amide groups→urethane groups→isocyanuric acid rings.
